"Bistability in the 60 cm Sodium Experiment"

by Matthew Adams

Friday, April 9, 2010 -- 12:00 p.m.
Large Conference Room, 1207 Energy Research Facility

Advisor:  Professor Daniel Lathrop

The 60 cm sodium experiment is a spherical-Couette device used to study the behavior of rotating, conductive fluids in a geometry that approximates that of the core of the Earth. By this we hope to better understand the dynamo effect that gives rise to the magnetic fields found in many planetary and astrophysical bodies. In this talk I will describe some recent experiments motivated by hydrodynamic phenomena seen in the 3-meter spherical-Couette waver experiments. I will also talk about some hydromagnetic phenomena seen in these experiments with stronger applied magnetic fields, which may be related to the magnetorotational instability.
